Variation in wood specific gravity of selected tree species of Kohima district of Nagaland North Eastern parts of India
Keduolhouvonuo and Hemant Kumar
The basic quality indicator for most of the wood properties is wood density and moisture content. Wood density steadily has the most influence on mechanical properties, particularly stiffness. It has an influence on many of the mechanical/physical processes during manufacture. A study was conducted to determine moisture content, wood specific gravity and ash content of branch and stem samples of most commonly found 15 species of Kohima, Nagaland. Findings of the present study revealed significant variation between branch and stem for different parameters. The study showed that the species with the highest moisture content for both stem and branch was Albizia chinensis
(60.88% and 63.11%) while minimum was in Quercus pachyphylla
(31.16 and 32.05%), maximum ash content in branch of Terminalia myriocarpa
(2.68%)while stem ash content was higher in Cedrela serrata (0.65%). Minimum ash content recorded in Albizia procera (1.34%) and Macaranga peltata (0.26 %) for branch and stem respectively. The species with maximum specific gravity found for the branch sample was Quercus serrata (0.69) and the minimum was in Alnus nepalensis (0.35) whereas stem samples of Quercus serrata, Quercus pachyphylla and Myrica nagi recorded highest specific gravity (0.70) while the minimum was exhibited by Alnus nepalensis (0.36).
